4692 5606 d 11 h svoboda /branches/tracing/ Merge trunk changes up to r4686.  
2787 6116 d 13 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2586 6265 d 7 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2568 6292 d 23 h jermar /trunk/uspace/ Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril.
 
2483 6389 d 14 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.
 
2482 6390 d 5 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6390 d 7 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.
 
2479 6394 d 16 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2071 6551 d 9 h jermar /trunk/ (c) versus (C)  
1866 6686 d 9 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1787 6741 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1653 6775 d 10 h cejka /uspace/trunk/ Doxygen comments.  
1610 6776 d 15 h palkovsky /uspace/trunk/ Revised ipc. Now it is preferrable to use only functions from async.h, they
take care of correct buffering, waiting for answers etc.
 
1427 6786 d 7 h palkovsky /uspace/trunk/ Added functions to async framework for reasonable sending asynchronous
messages.
 
1392 6792 d 10 h palkovsky /uspace/trunk/ Merged libadt into libc.
Made lot of psthread and thread stuff thread-safe.
Added new driver framework for easy C connection programming.
Changed FB code to use new API.
 
1129 6850 d 15 h palkovsky /uspace/trunk/ Completed support for TLS in GCC (modifier __thread) for ia32,amd64,ia64 and mips.  
1128 6850 d 16 h jermar /uspace/trunk/ Improve comments in psthread.c
Rename pt->list to pt->link.
Rename ps_preempt() to psthread_schedule_next().
Rename ps_join() to psthread_join().
 
1125 6850 d 19 h jermar /uspace/trunk/ TLS and pseudo thread support for ia64.  
1113 6851 d 19 h palkovsky /uspace/trunk/ Added symbolic links 'libarch','libadt','libipc' into libc/include,
so that it can be easily used from anywhere.
Renamed thread_main to __thread_main.
Allowed MIPS to compile with -O0.
Added non-preemptible threads support (not yet secured by futexes).
Added simple way to hold Thread Local Storage. Support for compiler
will be added later.
This update breaks IA64 uspace.

There is some forgotten spinlock_lock() in futexes, amd64 gets locked
in the secod uspace thread probably with preemption disabled.
